2020 Subaru Ascent

The Transmission is slipping on my 2020 Ascent. I had the recall wrk-21 performed in July of 2025. Over the last 6 months the car has been hesitant to go at low speeds and shakes at high speeds. Over the last month the transmission started to slip while accelerating , especially up hill. There would be a grinding noise and RPMs would jump. I took it to the dealer and they confirmed it was the transmission via camera test. I called Subaru of America for goodwill help with the cost knowing that there is a know issue with the transmission. They refused due to the mileage, 121,010. •What component or system failed or malfunctioned, and is it available for inspection upon request? The transmission is slipping •How was your safety or the safety of others put at risk? The car is hesitant to go from a starting position. The car will jerk back and forth when trying accelerate when merging or crossing a road. I am also very concerned of catastrophic failure at high speeds. •Has the problem been reproduced or confirmed by a dealer or independent service center? The dealer has confirmed the transmission is bad via camera teat. •Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Just the dealership •Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No dash lights just the feeling and sounds.

My strut bearings have been replaced several times in the drivers sides, my shock and strut has been replaced twice on the drivers side and now the passenger side is doing the same thing. The dealership tells me that there is nothing wrong but research shows this car has known suspension issues. My passenger side front has a loud metallic grinding sound when turning the wheel in park. I’m told this is the brakes which makes no sense. The car feels like it is on ice or sailing down the road, and the car does not maintain an alignment causing the insides of tires to wear out after 15,000-20,000 miles and need to be replaced.

I am reporting a repeat safety concern involving a 2020 Subaru Ascent. The vehicle was involved in two separate collisions after failing to decelerate as expected following normal brake pedal application. The first incident occurred on January 26, 2026. While approaching a traffic signal, I applied the brakes under normal driving conditions. The vehicle did not slow as expected and struck the rear of another vehicle. Property damage occurred, but no injuries were reported. The second incident occurred on May 5, 2026. While approaching a stop sign at approximately 35 mph, I again applied the brakes under normal driving conditions. The vehicle did not decelerate as expected and entered the intersection, colliding with a vehicle traveling perpendicular to my direction of travel. Both vehicles were towed. No injuries were reported. During both incidents, there were no forward collision warnings, automatic emergency braking interventions, or other alerts observed prior to impact. Following the second collision, the vehicle was inspected by an independent technician. Brake components inspected were found to be within serviceable condition and no evidence of neglect or improper maintenance was noted. During inspection, abnormal brake pedal behavior was observed, including continued downward pedal travel while steady pressure was applied. The technician documented that the reported condition was not consistent with normal braking performance and stated that an intermittent hydraulic and/or brake assist related issue could not be ruled out. The vehicle has been regularly maintained according to manufacturer recommendations. Due to the repeat nature of the condition, the lack of warning or intervention from safety systems, and the occurrence of two collisions despite normal brake application, I believe this condition represents a significant safety risk. The vehicle has since been declared a total loss and may be available for further inspection.

I am submitting this complaint regarding a known exhaust manifold/flex pipe failure affecting my 2020 Subaru Ascent Touring (VIN: [XXX] ). My vehicle was diagnosed by a Subaru dealership with a “broken flex pipe on the header” causing excessive exhaust noise and exhaust leak concerns. Repair estimate was slightly over $2,000. After researching the issue, I discovered numerous reports from other Subaru Ascent owners describing identical failures involving cracked exhaust manifold welds and failed flex pipe sections. Subaru has also issued TSB 09-106-23 involving exhaust manifold weld cracking and redesigned replacement components for this issue. Symptoms began in the low 70,000-mile range and progressively worsened before formal diagnosis at approximately 83,000 miles. This appears to be a widespread defect involving emissions/exhaust components. Many owners online report loud cold-start exhaust noise, cracked manifold welds, failed flex pipe sections, exhaust fumes/smells, and expensive manifold replacement repairs. My concern is both the widespread nature of the defect and Subaru’s handling of complaints regarding the issue. Initially, Subaru denied assistance because the vehicle has a branded title. After documentation was provided showing federally mandated emissions-related coverage/extensions were active for this VIN regardless of title status, the denial basis changed to mileage. After explaining symptoms began prior to the mileage threshold, Subaru then cited lack of dealership service history after my ownership despite the vehicle being regularly maintained by a local mechanic. I am requesting NHTSA review whether this exhaust manifold/flex pipe defect represents a broader reliability and emissions-related defect trend affecting Subaru Ascent vehicles.

The pressure sensor coming out of the transmission has failed, and it's pushed transmission fluid throughout the engine harness, transmission harness, the bull harness in the dash and the 02 sensors. All of those have been damaged. The car is now unsafe to drive due to the pressure sensor failing. This information comes directly from the Subaru dealership. There was nothing prior to this that indicated there was a problem. I bought the car from a certified dealership 8 months ago and it was a certified pre owned vehicle.

The contact owns a 2020 Subaru Ascent. The contact stated that while driving on several occasions at various speeds, the steering wheel became loose and then tightened inadvertently. The vehicle was taken to a dealer where the failure could not be replicated. The contact also stated that on several occasions while driving, the vehicle puttered and a grinding noise was heard emanating from the engine compartment. The vehicle was towed to a dealer where it was diagnosed during the first visit to be the transmission module. The vehicle was repaired, but the failure persisted sporadically. The vehicle was taken back to the same dealer on the second visit where it was diagnosed that the transmission needed to be replaced. The vehicle was repaired, but the failures reoccurred approximately 5,000 miles later. The vehicle was taken to the same dealer on the third visit where it was diagnosed that the tie rod end and bushing needed to be replaced. The vehicle was repaired, but the failure persisted. The vehicle was then taken to the same dealer on the fourth visit where the failure could not be replicated. The vehicle towed to the same dealer on a fifth occasion where it was diagnosed that the transmission needed to be replaced. The vehicle was not repaired as of yet. The manufacturer was notified of the failure and a complaint was filed. The failure mileage was approximately 82,000.

In December 2025, I had brake replacement, tire service, and wheel alignment performed at Monro Auto Service located at [XXX] child were traveling on the highway during a winter storm when the brakes began making a loud banging noise. My wife was unable to immediately locate a service location and was forced to continue driving for an extended period in winter storm conditions while in fear for her safety and that of our child. When she was finally able to reach a second Monro location between [XXX] and [XXX] , a technician discovered that one brake caliper bolt was missing entirely and a second was dangerously loose. The vehicle had been driven at highway speeds in a winter storm with an improperly and incompletely assembled brake system for an extended distance before help was found. The second Monro location secured the caliper bolt and confirmed the vehicle safe to continue. The original Fairport location was contacted and their manager acknowledged the issue but has failed to provide any meaningful resolution after nearly four months. In a formal BBB complaint response, Monro Inc. confirmed that the caliper bolt had not been properly secured and acknowledged filing an insurance claim for resulting rim damage — an implicit admission of negligence. I am filing this complaint because an improperly assembled brake system — specifically a missing caliper bolt — represents a serious and potentially fatal safety hazard. If this is a pattern of negligence at Monro locations, other consumers may be at risk. BBB Complaint Case #XXX is on file documenting Monro's formal response and admission.

My 2020 Subaru Ascent struggles to retain power when accelerating, especially from stopping and especially when the fuel is low. The vehicle stalls or loses some power when trying to accelerate. The check engine light is not on and there is no other indication that there is a problem with the vehicle. I have discussed it thoroughly with my mechanic and we both think it sounds like a fuel pump issue. He looked at the other Subaru recalls and thinks my vehicle should be included in the other Subaru fuel pump recall (NHTSA ID Number: 21V587000). Does my vehicle qualify for this fuel pump recall? Thank you.
